PROCEDURE

实验过程

A solution of 4,5-dichloro-3-nitropyridin-2-amine (0.0365 g, 0.000175 mol) (Johansson, H; Lawitz, K; Nikitidis, G; Sjoe, P; Storm, P. PCT Int. Application WO2004/01661-1), (1R,3S,4S)-3-{[tert-butyl(dimethyl)silyl]oxy}-4-({[tert-butyl(dimethyl)silyl]-oxy}methyl)cyclopentanamine (0.0947 g, 0.000263 mol) and DIPEA (0.0907 g, 0.000702 mol) in ethanol (10.0 mL) was refluxed overnight. The reaction was concentrated and purified by flash chromatography (30% EtOAc/hexanes) to afford the title compound (0.0768 g, 82%) as a yellow solid.
